Hi -
I'm having a problem booting a Dell 486P/50 (486DX2/50) w/16MB memory,
Adaptec 1542CF (IRQ 11, DMA 5), Quantum LPS525S SCSI disk (501MB) and
3COM 3C509 (EtherLink III) from the FreeBSD 2.0R (941204) boot floppy.
It sees all the devices, but after the "Changing root device to fd0c"
message, it craps out with:
Fatal trap 12: page fault while in kernel mode
fault virtual addr = 0x7
fault code = supervisor read, page not present
intruction pointer = 0x8:0xf0107560
Code segment = base 0x0, limit 0xfffff, type 0x1b
DPL 0, pres 1, def32 1, gran 1
Proc eflags = int enabled, resume, IOPL = 0
Current proc = 0 ()
int mask = net tty bio
panic: page fault
We tried turning off ROM and video BIOS shadow and caching... no luck.
Anyone seen this before or have suggestions on getting this machine up?
Thanks!
- Mike
